2 Claims. (Cl. 224-) This invention relates to a device for use principally by firemen in fighting fires and aiding in rescue work and more particularly to a sling adapted to numerous uses including the relief of the strain encountered while hold ing and controlling a hose with a high nozzle pressure.

An object of this invention is to provide a very simple and inexpensive double loop sling which will be of great assistance to firemen in the various tasks they are called upon to perform in the line of duty.

Another object of this invention is to provide a device which may be worn while not in use without any inconvenience to the person and without interfering in any way with ordinary body movements. A device which may be employed in various ways and which will prove of great assistance to firemen as a short rescue line; for carrying sick and unconscious persons; for carrying a roof rope or extinguishers up a ladder; as a hose strap or pipe holder; to carry bulky objects from buildings; to lighten hose lines; in operating a line from a ladder; to lower persons from a higher to a lower level; for attachment to a ladder to prevent falling therefrom, and numerous other ways which will suggest themselves as occasion arises.

Another very important object of this invention is to provide a device which may be worn by firemen while riding on or in the cabs of fire engines to secure them to the fire engines so that they will not be thrown therefrom in case of sudden stops, accidents or sharp turns.

Specific illustrations of our invention are shown in the accompanying drawings, wherein:

Fig. 1 is a perspective view illustrating the manner in which the sling may be employed to relieve the strain of holding and controlling a hose nozzle with a high nozzle pressure;

Fig. 2 is a perspective view illustrating the manner in which the sling is attached to a hose;

Fig. 3 is a perspective view of the sling embodying the invention;

Fig. 4 is a plan view in detail of the ring and snap hooks showing one embodiment of the manner in which the body strap and sling strap are connected thereto; and

Fig. 5 is an elevational view in detail, taken on lines 55 of Fig. 3, showing the ring, snap hook and means for adjusting the length of the sling strap, and the manner in which the body strap and sling strap are interconnected.

The device embodying the present invention includes an arm loop 1 adapted to slide over the users arm and rest on his shoulder. It should be understood that this loop may be made in any desired length and of any material suitable for the purpose. A preferred embodiment of this arm loop is an overall length of approximately 3 feet. In general, the preferred material is canvas that is 1 /2 inches wide and resistant to water and mildew. Each end of this loop is turned back upon itself, as indicated at 2, in order to provide a means for connecting a ring 3 to these ends to form the closed arm loop 1 that may be conveniently hung over one shoulder.

The device further includes a second or sling loop 4. This loop is folded upon itself at both ends, as indicated at 5, to provide a means for securing snap hooks 6 thereto. The snap hooks are attached, when desired, to the ring 3, to form the second loop 4. A buckle 7 may be provided intermediate the ends of loop 4 to provide a means for adjusting the length of this loop. The sling loop 4 may be made of any desired material suitable for the purpose and in any desired length. The material, in general, is the same as that used for the body strap, and for purposes of this invention it is preferred that the sling strap be adjustable to at least seven feet in length.

In the ordinary duties of a fireman many occasions arise where he is called upon to lift or move heavy bulky objects, or where both hands are not free to operate fire fighting equipment since he is holding on to a ladder with one hand. Also on many occasions men are diverted from other tasks in order to aid in holding and controlling a hose nozzle with a high nozzle pressure. The device of the present invention overcomes all of these obstacles as it can be adapted to aid in lifting objects of any configuration, to secure a fireman to a ladder and to aid in holding a high pressure nozzle.

The device may also be worn while not in use without any inconvenience to the person. For this purpose one arm is inserted in the arm loop and the loop is rested on the shoulder. The sling loop is then adjusted around the waist of the wearer and held snug to the waist by means of the snap hooks 6 which engage the ring 3.

One of the uses of the sling of the present invention is illustrated in Figs. 1 and 2. Ordinarily several men are required to hold and control a high pressure hose of the type, used in fire fighting. With the device of the present invention one man can safely operate a nozzle with a pressure up to pounds, without the necessity of others helping him. For this purpose one arm is placed through the arm loop and this loop is positioned on the shoulder. One end of the sling strap is disengaged from the ring 3, the sling strap is wrapped around the hose 3 and the free end is reengaged with the ring. Three turns around the hose will suflice for ordinary purposes.

Having thus described our invention, we claim:

1. In a device of the class described, an arm loop having its ends permanently fastened to a ring, and a sling loop with a snap hook permanently fastened to each end thereof, said snap hooks being adapted to hold onto the ring attached to the arm loop whereby said sling loop is formed when both hooks are hooked to said ring.

2. In a device of the class described, an arm loop having its ends permanently fastened to a ring, and a sling loop adjustable in length with a snap hook permanently fastened to each end thereof, said snap hooks being adapted to hook onto the ring attached to the arm loop whereby said sling loop of adjustable size is formed when both hooks are hooked to said ring.
